To all 'whom it may concern: Beit known that I, FREDEmcK' C. TAxIs, citizen of the United States, residing at St.` Louis, State of Nissouri, have nvented certain new and useful Improvements in ConcreteFloor Construction, of which the following is a full, clear, and exact description, reference being had to the accompanying drawings, forming a art hereof.

My invention has re ation to improvements in concrete-floor constructions; and it consists in the novel details more fully set forth in the specfication and pointed out in the v claims. I

1 In the drawings, Figure 1 is a vertical section of'a concrete floor Showing my invention applied thereto, the section being on the line 1-1 of Fig. 2, and the concrete being shown dotted; Fig. 2 is a section at right angles to Fig; 1, being a section on line 2-2 of F ig. 1; Fig. 3 is an enlarged section on the order of Fig. 1, showing the concrete in full; Fig.` 4 is a verticalsection on line 4- -4 of Fig. 3; and Fig. 5 is a erspective of one of the trans- The present invention is a division of my ending application for patent on concreteoor constructions, filed July 27, 1907, Serial Number .385,842, and like it has for its object to introduce into a concrete floor censtruction a structural detail which shall not only serve to properly space and tie the metallic reiniorcing and supporting bars for the concrete, but shall at the same time serve as a ag? for the onstruction of the boxing into w ic the cement com osition is poured around the bars previously spaced and ositioned. With my improvement any shiiling of the r'einforcing members is impossible, a

a umform construction is obtained.

In detail the invention may be described as follows: Referring to the, drawings, P, P,

represent concrete (or other) illars for the support of the concrete floor, t e latter tgeng made up of suitable cement composition C, and a series of su porting and reinforcing bars or members a respectively, having upturned ends a/ b' respectively, the said members forming the sup orts for the floor, the ends thereoi resting irectly on the pillars P where the latter arerestored to, or on I- beams or equivalent structural members (not here illustrated as they are fully understood in the art). The body or main'por- 429,&00.

tions of the members a b are disposed in 'the same horizontal plane at e ual distances from the opposite faces of t e completed floor as shown, the cement being as well understood, tem orarilv laid on and su ported bythe false oor or .boxin B, whic is removed when the concrete l as fully set"and hardened.

In the Construction of the floor the supporting and reinforcing members are (as well understood) lad With their opposite ends over the pillars (or structural members) and' disposed parallel to one another at predetermined distances 3)&1'13. To insure permanent parallelism t erefor and prevent displacemcnt thereof, I tie the several members a b together by means of a series of cross spacing members or tie-bars which in the present form of my invention are in the shape of metal strips -1 provided with depending U-shaped bends 2 on either side of which, and on opposite sides of the strips, are dis'- posed the arms or anchors 3, 3, cut from the ody of the strip, the depth of the cut being indicated by the offsets 4, and the length of the cut extendng from said oil'sets to the points where 'the bends merge with the body of the strip. The anchors 3, and bends 2 whicheonstitute the spacing legs or gages between the boxing and tie members are thus formed ntegrally with said tie members From the manner of their formaton, the anchors 3 obvously and neccssarily are disposed on opposite sides of the long-itudinal center of the strip 'By concrcte" floor constructions, I of course wish to include any and all floors or walls of a composite character, that is, those composed of composition, concrete, or cement reinforced by metal, the term conerete being heren used in its broadest scarse. It is obvious of course that the tie members 1 need not necessarily be at right angles to the rei'forcing members a b. The tie-bars 1 are connected to the members a b 100 by folding the arms or anchors 3, 3, about the members as shown in the drawing. The members a b are thus superposed directly over the tie members 1, the spacng legs or gages 2 serving to space the roof of the bx- 105 ing a fixed distance from the reinforcng members, the legs`thus performing the funetion of gages which determine the depth of the concrcte below the planes of the reinforcing members, the beses 'of the legs com- 110 I stituting V-shaped legs, and arms on either l ing in contact With the boxing as the letter is undergoing Construction. and coming fiush With the under surface of the conorete portion of the floor When the letter is finished.

Having described my invention what I claim is 1. A eombnation tie and gege member for a concrete floor Construction, comprising e strip having a series of bends formed -in the body thereof, and disposed et intervals alon the same, constituting V-shapod legs, and arms on ,either side of the V-sheped spaces, cut from the body of the original strip oh opposite sides of said strip, sidmtertially as set forth.

'2. In eombination With a reinforeing mernber of a eonerete floor, a eombinaton tie and gege member disposed below the same and transverse thereto, eonr rising a str p h eving a series of bends formec-` in the body thereof and dsposed at ntervals along the same eonside of the V-shaped spaces, cut from the body of the original strip on opposite sides of said strip, end folded over the reinforeng member, suhstantinlly as set forth.

3. In combina tion With e reinforcng Inemher of conerete floor, a tie member or strip having a series of suitbly speeed U-sharped bends formed i'tegr dly therewith and (le-- pending therefron across the entire width thereof, 2111 :mc-hor arm cut or for-med, from the tie-meniher along each edge thereof nt points eoniiguous to the mergcr of the hends with the body of the tie-member, said :rnehors being of suitable length to ermit the same to he rolded about the roinforeing member, suhstzmtinlt* as set forth.

in tcstimony ndzereof I afiix my signrture, presence oi two witnesses.
